Our Zinc Business

As one of the world’s largest producers of zinc, Teck plays an important role in supplying zinc to meet the world’s
infrastructure needs. We are also supporting zinc as an essential micronutrient to protect human health and as a soil
additive that can significantly improve crop yields.

Zinc accounted for 27% of our business in 2014.

Our Zinc Operations

We are one of the world’s largest producers of zinc, primarily from our Red Dog mine in
Alaska and Antamina mine in northern Peru. Our metallurgical complex in Trail, British Columbia is
also one of the world’s largest integrated zinc and lead smelting and refining operations.
In total, we produced 659,700 tonnes of zinc in concentrate while our Trail Operations
produced 277,400 tonnes of refined zinc in 2014.

Our zinc portfolio also includes the Pend Oreille mine in Washington State, which was restarted in December of 2014.

Our Zinc Product

Zinc is one of the world’s most widely used base metals.
For over a century, it has been used to protect steel against corrosion,
improving its durability and extending its life; this remains its primary
use today. Zinc is also important in producing brass and bronze, and in
die-casting to produce thousands of consumer and industrial products.

Zinc is an essential nutrient for humans and other living things.
It can help to reduce illness and improve the health of children,
particularly in developing nations where diets may be lacking in zinc.
It can also be used in fertilizer to improve crop quality and quantity where soil is zinc deficient.

Demand Outlook

Zinc is one of the world’s most widely used base metals and as global
urbanization continues to grow so too will demand for zinc. Zinc is
integral for many of the products we rely on in today’s society like
automotive parts and construction materials like galvanized rebar.

In the short term, closures of large zinc mines will continue into 2015,
while demand is expected to continue to grow, leading to a tightening global zinc market.
Teck is well positioned to take advantage of this with our restarted Pend Oreille mine
and existing production from Red Dog and Antamina mines.
